Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to the rear structure of a Western-style toilet.

(Conventional Western-Style Toilet) FIG. 3 is a partially cutaway side view showing a Western-style toilet of a type in which a cover 4 for a low tank 8 is integrally provided at the rear of the toilet main body 1. The Western-style toilet has a hot water washing device and a hot air drying device housed inside the rear part of the toilet main body 1. The hot water cleaning device cleans the anus and the like by jetting hot water, and includes a cleaning device 2, a hot water tank 3, a pump, a solenoid valve, a temperature controller (all not shown), etc. It consists of the following equipment. The hot air drying device is for drying the buttocks wetted by the hot water washing device, and is composed of a blowing fan 5, a blowing nozzle 6, a heater (not shown), etc. Consists of.

(Problem to be solved by the invention) It is preferable that the blowing nozzle 6 of the hot air drying device is positioned directly above the washer 2 of the hot water washing device in the toilet bowl 1a. The fan 5, which is the main component of the drying device, is installed at a position away from the blow-off nozzle 6, and both are connected to the duct 7.
I had to connect it by. This is because, within the limited storage space, the respective components of the hot water washing device and the hot air drying device are installed in a harmonious manner by making good use of the mutual spacing between the components. For this reason, in hot air drying equipment, the pressure loss of hot air increases, and the fan 5
needed a large one. In addition, as mentioned above, since the components of the hot water washing device and the hot air drying device are installed intertwined with each other,
In order to perform maintenance on either of these devices, some or all of the instruments in the other device had to be removed, which was a hassle.

The present invention was developed in view of the above circumstances, and is a new rear structure of a Western-style toilet that allows maintenance of both the hot water washing device and the hot air drying device to be performed easily and independently. (hereinafter referred to as the merits structure).

``Structure of the invention'' (Means for solving the problem) The gist of the invention is that a storage chamber for the pump, tank, and other equipment constituting the hot water cleaning device is provided independently inside the rear part of the toilet bowl body. In addition, a recess is provided in the area corresponding to the seat of the hinge box for the toilet seat, which is placed on the rear upper surface of the toilet main body, to accommodate part or all of the fan that is the main component of the hot air drying device, deodorizing device, etc. The concave portion is in internal communication with a vent opening toward the inner surface of the toilet bowl.

(Function) The hot water washing device is installed in a storage chamber provided independently inside the rear part of the toilet bowl body. Further, the hot air drying device is housed in a recess provided in the rear upper surface of the toilet bowl body. In other words, the storage spaces for both devices are completely different, and the other device does not interfere with maintenance of each device. In addition, the recess that houses part or all of the fan of the hot air drying device is internally connected to a vent that opens toward the inside of the toilet bowl, so that the fan is close to the toilet bowl. It's summery. Therefore, there is almost no pressure loss of hot air, and it has become possible to downsize the fan.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a side sectional view showing the proposed structure. The most distinctive feature of the proposed structure is that a storage chamber 10 is provided inside the rear portion of the toilet main body 9, and a recess 11 is provided in the upper surface 9b.

The storage chamber 10 is for storing a hot water cleaning device (consisting of a cleaning device 2, a pump 12, etc.) as shown in FIG. As shown in FIG. 1, the storage chamber 10 is located on the rear upper surface 9b of the toilet main body 9.
It has a wide opening 10a, and is an independent space surrounded by walls all around. Further, among the peripheral walls forming the storage chamber 10, a mounting hole 10b for the washer 2 is bored in a vertical wall surface 9c which also serves as a part of the wall of the toilet bowl 9a.

The recess 11 is for accommodating the lower part of a fan 13, which is the main component of the hot air drying device, as shown in FIG. The recess 11 is located on the rear upper surface 9b of the toilet main body 9 so as to open into a region corresponding to the seat surface of a hinge box 15 that maintains the upward movement of the toilet seat 14. It is designed to be stored inside a box 15. As shown in FIG. 1, the recess 11 is internally communicated with a vent 11a that opens toward the inside of the toilet bowl 9a, and the rim water passage 9d in the area where the vent 11a is provided is shaped like a step. It is becoming. As shown in FIG. 2, a blowing nozzle 6 of a hot air drying device is inserted and fixed into the vent 11a. In addition, the reference numeral 16 in the figure is a shutter that prevents urine or the like from entering into the blow-off nozzle 6.

With this proposed structure, as shown in Fig. 2, maintenance of the hot water washing device can be performed by removing the low tank cover 4, and maintenance of the hot air drying device can be performed by removing the toilet seat hinge box 1.
This can be done by removing 5.

(Study of another aspect) In the embodiment, only the hot air drying device was explained, but the deodorizing device etc. is also mainly composed of a fan, and the deodorizing device is installed in the recess provided on the upper surface of the rear part of the toilet bowl body. It may also be possible to store the . In addition, although the drainage path structure of the toilet shown in the example is a siphon type, this is not limited to this, and it does not matter whether it is a vortex type, a siphon jet type, or a flushing type. . Of course, the presence or absence of the low tank cover is not limited at all. in this way,
The structure and shape of the proposed structure can be changed as appropriate depending on the mode of implementation.

"Effects of the invention" As is clear from the above explanation, the rear structure of the Western-style toilet according to the invention simplifies maintenance of the hot water washing device and hot air drying device (or deodorizing device), and during the work, On the other hand, there is no need to go through the trouble of removing the equipment from the device. In addition, since the fan of the hot air drying device or deodorizing device is positioned close to the toilet bowl, there is less pressure loss up to the outlet, and the fan can be made smaller accordingly. It has many excellent advantages.
